Dual Snorkel

OPERATION
The dual snorkel air cleaner performs like a single snorkel air cleaner except on deep throttle acceleration, when both snorkels are opened as manifold vacuum drops below 5" Hg.

The "non-heat" air snorkel is connected to manifold vacuum through a tee in the vacuum hose between the carburetor and the sensor.

Verify the second snorkel vacuum diaphragm is the one with the heat connector.
